Battery life vs data transfer
For the US:
If you don't travel heavily, don't need broadband and live in an area with good GSM coverage then GSM is a no brainer. The battery life is better and you don't have to fiddle with phonebook transfer programs and the like.
If you need coverage and broadband then CDMA is the way to go.
My gripe with CDMA is that it takes forever to get good phones. You wait and wait for someone to make a CDMA phone that has year old GSM features.
If CDMA could fix the talk time and get manufacturers to make phones for it I would say that CDMA wins, period. As it stands though, if you live outside of the US, or live in the US and don't travel or just use your phone for talking, SMS and the occasional MMS then GSM is for you.
Basically I just want a world standard. If that means CDMA has to switch over and I lose some bandwidth, so be it. It look like Europe is flirting with (W)CDMA, so maybe GSM will be phased out. I guess it's market share vs technology at this point.
